I have PC with Processor, Rayzen9 3900xt, 3.8G, 12 core and 48G Ram. I write code to solve partial differential equation. My PC is new and take long time about 5 hours without compute any thing. My Colleague has PC i7 Processor 3.6 G speed, 4 core. He take about 53 min to obtain the computational results by using the same code!!!. We use the same version Mathematica 12.2. I need help to under stand what is the problem?.
